7(x + 2) = 6(x + 5)
7x + 14 = 6x + 30
x + 14 = 30
x = 16
100%/x%=32.2/24.15
<span>(100/x)*x=(32.2/24.15)*x - </span>we multiply both sides of the equation by x
<span>100=1.33333333333*x - </span>we divide both sides of the equation by (1.33333333333) to get x
<span>100/1.33333333333=x </span>
<span>75=x </span>
x=75
<span>now we have: </span>
<span>24.15 is 75% of 32.2</span>
The required equation of a line is y = -3x- 1
<h3>Equation of a line</h3>
The equation of a line in slope-intercept form is expressed as:
y = mx + b
where
m is the slope
b is the y-intercept
Using the coordinate point (0, -1) and (-1, 2)
Slope = 2-(-1)/-1-0
Slope = 3/-1
Slope =-3
Since the line crosses the y-axis at (0, -1), hence the value of b is -1
Determine the equation
y = mx + b
y = -3x + (-1)
y = -3x- 1
Hence the required equation of a line is y = -3x- 1
